The process of developing capitalism has taken millennia and in the last few centuries has had far more intellectual horsepower put into it than developing phones. Lots of iterations have been tried, it can't be compared to a beta product at all. The major problem we have on that front is people keep trying to regress backwards to models of organisation that have already been tried and are well understood not to work effectively - because almost nobody votes based on historical learnings.
Once we have >100 years experience in building phones there probably won't be annual upgrades any more either, it'll be like-for-like replacements.
